农五师引进外资开发荒地30万亩。以往,开荒地土壤洗盐采取的是淹灌方法,但淹灌洗盐周期长,平整土地工作量大,洗盐用水多,地力培肥慢,耗费劳力多。为加快开发速度,必须找到一种既省水又缩短周期的新方法。为此,我们设想用喷灌和生物措施相结合的方法改良盐碱土(以下称改土)。试验面积为60亩,并于1987年5～9月进行了试验,取得了较好的效果。
Five agricultural division to introduce foreign investment to develop wasteland 300000 mus. In the past, land reclamation of salt ponds is a method of flooding irrigation, but flooded irrigation salt cycle is long, flat land workload, salt water use more fertility slow fertilization, labor and more labor. To speed up the development, we must find a new way to save water and shorten the cycle. To this end, we envisaged the improvement of saline-alkali soil (hereinafter referred to as soil modification) by a combination of sprinkling and biological measures. Test area of 60 acres, and in 1987 from May to September were tested and achieved good results.
